Cacti
I am a member of GroenLinks (the Dutch Green party). I like nature. So I'd like to have a lot of plants in my house. However, there is one problem: Plants usually don't live very long when I have to take care of them. I put them in the wrong place, don't give them enough water or give them too much water. Sometimes both at the same time. Most of the time I'm glad I'm able to keep myself alive.
So, I don't have a lot of plants in my house. Actually I've only had one normal plant which lasted longer than a few months. I have it in one of those pots with a water reservoir, so it shouldn't die from thirst or drown. It's lasted for several years, but lately even that looks like it's dying (slowly).
Basically the only plants that seem to have any chance to survive in my house are cacti. These cacti I've had for a few months now. They're in a normal pot and so far they look fine.
